Only if the exact model provides an appropriate function and its instructions allow the intended task. A warmer target or holiday setting is not the same as safe electrical isolation.
What the observation tells you
The appliance may share electrical and cooling components between compartments. Treating one section as disconnected can create risk during cleaning or servicing. Food in the other compartment also needs a plan if the whole unit must be isolated.
A useful next step
Follow the documented cleaning procedure and arrange alternative storage where necessary. Do not remove covers or touch electrical fittings because one screen says off.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
